Fullstack Dev Skills Plugin
by Jeffallan
This Claude Code plugin adds dozens of framework- and language-specific skills, plus multi-step workflows, so Claude automatically pulls in the right expertise for full-stack work.
Install plugin
/plugin marketplace add jeffallan/claude-skills && /plugin install fullstack-dev-skills@jeffallan
About
Jeffallan's claude-skills plugin (installed under the name fullstack-dev-skills) packages 67 specialized skills across 12 categories, including languages, backend and frontend frameworks, infrastructure, APIs, testing, DevOps, security, data/ML, and platform-specific expertise, that activate automatically based on what you ask Claude Code to do. Mention JWT authentication in a NestJS API, for instance, and the NestJS Expert skill engages along with the relevant authentication reference material, without you having to name or load anything manually.
Beyond individual skills, it defines named multi-skill workflows for common software lifecycles: a feature-development chain (Feature Forge to Architecture Designer to Fullstack Guardian to Test Master to DevOps Engineer), a debugging chain (Debugging Wizard to Framework Expert to Test Master to Code Reviewer), and a security-hardening chain (Secure Code Guardian to Security Reviewer to Test Master). It also ships nine project-workflow commands covering an epic's lifecycle from discovery to retrospective, including built-in Jira and Confluence support, plus a /common-ground command that surfaces and validates Claude's assumptions about your project's architecture before it starts making changes.

Frequently asked questions
Do I need to manually invoke each skill by name?
No. Skills activate automatically based on the content of your request, such as naming a specific framework or task.
Does this only help with writing code, or also with project management?
Both. Alongside framework-specific coding skills, it includes nine workflow commands for managing an epic's lifecycle, with Jira and Confluence integration.
